Plateflow – gasketed plate & frame heat exchanger SEMI-WELDED

Plateflow – gasketed plate & frame heat exchanger SEMI-WELDED

Semi-welded Plateflow design utilizes two plates laser welded together to form a cassette. The cassettes form channels within which the fluid flows. One fluid flows within the welded cassette, the other fluid between the welded cassettes. Two ring gaskets and a field gasket are used between adjacent cassettes. This design reduces the welded-side’s exposed gasket surface by approximately 90%.

Plate and Frame heat exchangers use a combination of chevron-style heat transfer plates sequenced between a frame plate and pressure plate. The heat transfer plates have holes at the four corners forming a header that distribute the respective flows to the opposite sides of each plate when the plates align. Semi-welded designs available in 2.5″, 4″, 6″, 8″ 12″ and 18″ connection sizes.

Materials: 304 and 316 Stainless Steel, Titanium, SMO 254, Hastelloy, Incolloy, AL6XN Plates. Field gaskets in Nitrile, EPDM, Viton, high temperature EPDM and high temperature Nitrile. Ring gaskets in Nitrile, EPDM, Chloroprene, PTFE coated, and Viton. Other materials upon request.

Applications: For close temperature approach of fluids for heat recovery applications. Semi-welded Plateflow exceptional for refrigerant, aggressive chemical, or any applications where reducing the fluid’s contact with elastomers is desired.

Features and Benefits:

  • Higher surface area to volume ratios than conventional shell and tube heat exchangers
  • Superior heat transfer coefficients compared to shell and tube heat exchangers
  • Offers “true” countercurrent flow, which maximizes the mean temperature difference between fluids
